**Estimated Current Return ("ECR") is computed by dividing the net annual
interest income, after annual expenses, by the public offering price.

**Estimated Long-Term Returns ("ELTR") represents an average of the yields to
maturity (or call) of the bonds in the Trust's portfolio under accepted bond
practice, adjusted to reflect expenses and the Trust's applicable sales
charges. ECR and ELTR calculations are based on the current market value of the
bonds in a Trust's portfolio and thus these perfermance measures will fluctuate
with market changes or changes in the composition of the Trust's portfolio.

Investing involves risk; principal loss is possible. There is no assurance that a unit investment trust will achieve its investment objectives. An investment in a unit investment trust is subject to market risk, which is the possibility that the market values of securities owned by the trust will decline and that the value of trust units may therefore be less than what you paid for them. Accordingly, you can lose money investing in a trust.
